Maintaining the correct pH range is crucial for effective nutrient absorption. During the flowering stage, plants are particularly sensitive to pH fluctuations, and poor adjustment can lead to nutrient lockout, especially for phosphorus, potassium, and magnesium.
CANNA pH- PRO Bloom contains 59% phosphoric acid (H₃PO₄) and is formulated to reliably reduce and stabilize the pH of your nutrient solution within the ideal range of 5.2 to 6.2. This ensures optimal uptake and metabolic performance during flowering.
Highly concentrated and intended for professional use, this solution provides precise control for hydroponic, coco, or high-performance systems.
✔️ Ensures optimal nutrient absorption during bloom
✔️ Targets the ideal pH range for flowering (5.2 – 6.2)
✔️ Prevents phosphorus and potassium lockout
✔️ Highly concentrated for long-lasting use
✔️ Suitable for advanced cultivation setups
Shake well before use.
Add 0.5 ml of pH- PRO Bloom per 10 L of nutrient solution.
Mix thoroughly and measure pH.
Repeat if necessary until target pH is reached.
Always wear protective gear (goggles, gloves).
Do not mix directly with other concentrated products.
